Mount Kōya: Okunoin, the Garan and a night in a temple

Mount Kōya, or Kōya-san, is a monastic town set in a high forested basin in Wakayama Prefecture, south of Osaka. It was founded in the ninth century by the monk Kūkai — known posthumously as Kōbō Daishi — as the headquarters of Shingon, the esoteric school of Japanese Buddhism, and it remains a working temple settlement of well over a hundred temples. It is part of the UNESCO-listed ‘Sacred Sites and Pilgrimage Routes in the Kii Mountain Range’.

This is a moderate day: the walking is mostly gentle and on good paths, but the mountain sits at roughly 800 m, the air is cool, and distances add up. The great pleasure of Kōya is to slow down and stay the night.

Getting there. Most visitors ride the Nankai railway from Osaka to Gokurakubashi, then the cable car up to the basin and a bus into town. Pilgrims have long walked up instead on the Kōyasan chōishi-michi, a stone-marked trail of about 24 km climbing from Jison-in temple at Kudoyama — you can join the last stretch or walk the whole thing over a long day.

Permits & tickets. No permit needed. Okunoin and the Garan grounds are free to walk; some halls and Kongōbu-ji charge a small admission. Temple lodgings are booked in advance.

Good to know:

Photography is not allowed beyond the Gobyō-bashi bridge, in the most sacred inner precinct of Okunoin.
Nights and early mornings are cold even in summer, and snow closes in through winter — pack warm layers.

Segments

Arriving on the mountain 1.5 km 📍 Map

Kōyasan basin (cable car / bus, or the chōishi-michi trail) → Ichinohashi bridge

Town streets, or mountain pilgrim trail

Most arrive by the Nankai cable car and a short bus ride; pilgrims climb the Kōyasan chōishi-michi, a trail of about 24 km marked by stone stupas set roughly every chō. Either way, begin at the Ichinohashi bridge, the traditional entrance to the Okunoin approach.

About this place

Kōyasan chōishi-michi (高野山町石道) is a pilgrimage route on the Kii Peninsula in the Kansai region of Japan. It begins at the Jison-in temple in the town of Kudoyama on the south bank of the Kinokawa River and extends twenty-four kilometres to Mount Kōya, or Kongōbu-ji Temple, the ecclesiastical headquarters of the Kōyasan sect of Shingon Buddhism in the town of Kōya. The path is a National Historic Site and is also part of the UNESCO World Heritage Site: Sacred Sites and Pilgrimage Routes in the Kii Mountain Range. The area is also within the Kōyasan Chōishi-michi Tamagawa Prefectural Park (高野山町石道玉川峡県立自然公園).

The Okunoin avenue 2 km 📍 Map

Ichinohashi bridge → Gobyō-bashi bridge

Stone-paved avenue under old cedars

The approach to Okunoin runs for about two kilometres beneath towering cryptomeria cedars, past more than two hundred thousand tombstones, memorials and moss-covered stupas — feudal lords, monks and merchants all buried close to the mountain's holiest ground. It is considered the largest cemetery in Japan.

Kōbō Daishi's mausoleum 0.3 km 📍 Map

Gobyō-bashi bridge → Gobyō (mausoleum) and Tōrō-dō

Sacred inner precinct, no photography

Beyond the Gobyō-bashi bridge lies the mausoleum of Kūkai, Kōbō Daishi, whom Shingon believers hold to rest here in eternal meditation. Before it stands the Tōrō-dō, the Hall of Lamps, where thousands of lanterns are kept burning. This is the spiritual heart of the mountain; photography stops at the bridge.

About this place

Kūkai , born Saeki no Mao posthumously called Kōbō Daishi , was a Japanese Buddhist monk, calligrapher, and poet who founded the esoteric Shingon school of Buddhism. He travelled to China, where he studied Tangmi under the monk Huiguo. Upon returning to Japan, he founded Shingon—the Japanese branch of Vajrayana Buddhism. With the blessing of several Emperors, Kūkai was able to preach Shingon teachings and found Shingon temples. Like other influential monks, Kūkai oversaw public works and constructions. Mount Kōya was chosen by him as a holy site, and he spent his later years there until his death in 835 CE.

A night in a shukubo 0.5 km 📍 Map

Kongōbu-ji → A temple lodging (shukubo)

Town streets

Many of Kōya's temples take in guests as shukubo, temple lodgings, with tatami rooms, a vegetarian shōjin-ryōri dinner and an early-morning Buddhist service you are welcome to join. Staying over is the classic way to feel the rhythm of the mountain.
